1'0 all whom it mag concern:

Be it known that I, WILLIAM THOMAS Mc- NARY, a citizen oftheUnitedStates, residing at San Jose, in the countyof Santa Clara and State ofCalifornia, have invented a new and useful Bicycle-Lock, of which thefollowing is a specification.

My invention relates to bicycle-locks, and has for its object to producea device of this character of comparatively simple construction whichwill be carried permanently by the bicycle and may be readilymanipulated for locking the latter or moved to its normal inactive andunobstructing position.

To these ends the invention comprises the novel details of constructionand combination of parts more fully hereinafter described.

In the accompanying drawings, Figure lis a side elevation of a portionof the bicycleframe having my invention applied thereto and illustratingthe parts in normal position. Fig. 2 is a similar view illustrating thebicycle locked. Fig. 3 is an enlarged detail sectional elevation. Fig. 4shows the device applied for looking a chainless Wheel.

Referring to the drawings, lindicat-es the center post or bar of abicycle-frame 2, which carries a sprocket-Wheel. 3 for operating thedrive-chain 4. These parts are of the usual or any preferredconstruction, inasmuch as they constitute no part of my invention.

In accordance with my invention I apply to the frame-bar 1, adjacent tothe sprocket- Wheel, a clip 5, preferably consisting of a pair ofsemicircular plates or sections hiugedly connected bya pint-1e 6,extended through 00- incident hinge-knuckles 7, formed upon therespective clip-sections, which are maintained in clamping position by ascrew 8.

9 indicates a chain which is attached to the clip 5, preferably byengagement of one of its links 10 with an eye 11, formed upon the endCarried by the chain 9 is a lock 12, having a perforated extension 13,

with which one of the chain-links ispermanently engaged.

14 designates a clip which is engaged with the frame-bar 1 at a pointabove and suitably remote from the clip 5 and comprises a pair ofsemicircular plates or sections hingedly or pivotally connected,preferably by a tubular pintle or member 15, extended through 00- actinghinge-knuckles 16, formed upon the clip sections, which latter aresecured in clamping position by means of a screw or the like 17.

18 indicates a longitudinally-movable rod or plunger extended centrallyand loosely through the tubular member 15 and provided at its normallyupper end with a thumb-piece or head 19 and at its lower end with a hookor its equivalent 20. This plunger is provided between its ends with afixed bearing disk or member 21, which engages the upper end of anormally-expanded spring 22, disposed within the tubular member 15 andbearing at its lower end upon the .bottom wall 23 of the member.

In practice the lock 12 is normallysustained in an unobstructingposition by engaging its shackle 24 with hook 20 of the plunger, whichlatter is acted upon by the spring for exerting an upward pull upon thelock of sufficient strength to prevent accidental escape of the latterfrom the hook and rattling of the parts. When in this position, if it isdesired to lock the bicycle the plunger is pressed downward "against theaction of the spring to permit disengagement of the shackle from thehook, when the shackle 24 may be passed through the sprocket-wheel 3 andaround the sprocketchain 4, as is usual. When, however, the device isemployed upon a chainless wheel, as in Fig. 4, the lock-shackle isengaged with one of the pedals.

From the foregoing it will be seen that I produce a device of simpleconstruction which will be eflicient inoperation, and one which isadmirably adapted for the attainment of the ends in View; but it is tobe understood that I do not limit myself to the precise details hereinset forth, inasmuch as minor changes may be made therein withoutdeparting from the spirit of the invention.

Having thus described my invention, what I claim is 1. The combinationwith a velocipede frame-bar, of a flexible connection attached thereto,a lock carried by said connection, a longitudinallymovable plungerconnected with the frame and operable for engagement with the lock, andmeans for maintaining said plunger yieldably under tension.

2. .The combination with a velocipede frame-bar, of a clip embracing thesame and comprising a pair of sections, a pintle pivotally connectingsaid sections and provided with an eye, a flexible member engaging theeye, a lock carried by said member, and a longitudinally movable plungerconnected 4. The combination with a velocipede frame-bar, of a flexiblemember associated therewith, a lock carried by said member, a clipembracing the bar and comprising a pair of sections, a tubular memberpivotally connecting the sections of the clip, a longitudinally-movableplunger extended through the member and operable for engagement with thelock, and a spring disposed within the tubular member and acting uponthe plunger to maintain the same yieldably under tension.

In testimony that I claim the foregoing as my own I have hereto aifixedmy signature in the presence of two witnesses.

WILLIAM THOMAS MONARY.
